EXHAUST-FAN.

Specification of Letters Patent.

Application filed February 14, 1912. Serial No. 677,442.

To all whom it may concern."

Be it known that I, SAMUEL REMBERT, a

citizen of the United States, and a resident of Memphis, in the countyof Shelby and State of Tennessee, have invented certain new and usefulImprovements in Exhaust-- Fans, of which the following is aspecification.

This invention is an improvement in exhaust fans and particularly inthat class of such devices illustrated in my former Patent No. 579,081of March 16, 1897, the present invention seeking to provide a novelconstruction by which the seed cotton or similar material handled by thefan may be discharged separately from the dust laden air drawn in by thefan, thus enabling the discharge of the seed cotton and of the dustladen air at different points and separately; and the invention consistsin certain novel constructions and combinations of parts as will behereinafter described and claimed.

In the drawing Figure 1 is a sectional plan view of a fan embodying myinvention. Fig. 2 is a sectional side elevation thereof.

Fig. 3 is a side elevation, parts being broken.

away and others shown in section.

In the present apparatus I employ a casing A, a fan B, and an inlet Ctogether with a perforated or foraminous guard plate D held to the fan Band revolving therewith, which parts are similar to corresponding partsin my former patent above referred to. By my present invention, however,I divide the outlet E by means of a partition plate F into channels Eand E In the operation of the fan, the material flows in the inlet 0,being drawn therein by the operation of the fan and the seed cotton'orother solid material which cannot pass through the perforated plate Dpasses down through the passage space E being aided in such operation bythe movement of the perforated plate, whilethe dust laden air passingthrough the perforated plate D is discharged at E to the outlet channelE the latter being separated from the channel E by the partitionplate Fas before described. This plate- F, it will be noticed from Fig. 1,extends inwardlyinto close proximity at F with the circumference of thefan and the plate is provided with ,a pearward extension F projectingunder the In practice the channel E may connect With an off-take pipe Ewhich may pass to the top of the building or other suitable dischargepoint while the channel F may be prolonged to deliver to a bin or otherreceptacle.

The invention is simple, facilitates the conveyance of the seed cottonor other malPatented Sept.3,1912.

terial to the desired point and operates to; 4

clean the same and to separate the cleaned material from the dust ladenair as will be understood from the foregoing description.-

In operation, it will be noticed that the dust in the air will be drawnagainst the side of the fan opposite the perforated guard plate so thatthe dust laden air will be discharged to the outlet channel E? while theseed cotton' or the like will be operated upon by the blast of air fromthe fan as most clearly shown in Fig. 1 of the drawing. I claim: I '1.An exhaust fan, substantially as herein described, comprising a fan casehaving'an inlet and an outlet, a fan within the fan case and having onits side next the inlet a perforated or foraminous guard held to' andrevolving with the fan and spaced from I the side of the fan casewhereby to provide a passage space within the case and extending fromthe inlet to the outlet and a partition plate approximately parallelwith the plane of perforated guard and arranged within the outlet andoperating to separate the material discharged from the passage spacefrom the dust laden air, etc discharged from the fan, the partitionplate having a rearward extension underlying and conforming to andresting in close proximity to the fan, substantia ly as set forth.

2. An exhaust fan having a fan case provided with an inlet and anoutlet, a fan within the case, a perforated guard forming with the fancase a space for material drawn inward by said fan and means dividingthe outlet into separate channels laterally side by side for thedischarge from said space and directly from the fan, substantially asset forth.

3. An exhaust fan comprising a fan case having an inlet and outlet, afan in the case, a perforated or foraminous guard plate secured to andrevolving with the fan and forming with the fan case a passage spaceleading from the inlet to the outlet and a partition plate in the outletand conformin edgewise to the fan and dividing the out et into separatechannels laterally side by side, substantially as set forth.

4. An exhaust fan having at one side a perforated or foraminous uardheld to and revolving with the fan an a casing inclosing said fan andhaving an inlet on its side next to the said guard, the casing beingalso providedwith an outlet and with a partition plate Within the outletand approximately parallel with the plane of the perfoee-wee is adaptedto receive the material checked by the erforated plate and the other the15 an disc arged directly from the fan, all substantially as and for thepurpose set forth. SAMUEL REMBERT.
